14 Claims.

My invention relates to railway cars and in particular to that type of car known as a dump car having doors forming the side walls of the body and opening outwardly and downwardly as and has for its object the provision of means for assisting the door controlling mechanism in holding the doors locked in closed position when the car is" in transit.

Another object of my invention is to provide a means for holding the door on the rising side of the body closed while the respective door controlling mechanism is out of engagement with the underframe of the car.

A further object of my invention is to provide a. means of maintaining the car body in position on the car underframe during abnormal service conditions.

Referring now to the drawings, Fig. 1 is a side elevation of a portion of a dump car'embodying my invention; Fig. 2 is a transverse section along the lines 22 of Fig. 1 showing in full lines the door controlling and locking mechanism with the associated parts of the car body shown in dotand-dash lines; Fig. 3 is a section taken along the lines 3-3 of Fig. 2 having the locking mechanism shown in full lines with the balance of the door controlling mechanism and car body in dotand-dash lines; Fig. 4 is a transverse section through the car body showing the body in fully tilted position and the door locking mechanism maintaining the rising door locked in closed position; Fig. 5 is a plan view of a portion of the underframe along the lines 55 of Fig. 4 showing the means for mounting the locking bars on 'the underframe; Fig. 6 is a transverse section through the car showing the preferred method of mounting the body on the underframe and the provision of means for pivoting the body on the underframe during the tilting of the car body; Fig. 'Tis a half-section similar to Fig. 6 and shows a modification of the method of mounting the body on the underframe.

Referring now in detail to the drawings where like reference characters refer to like parts, reference character i indicates a dump car having an-underframe 2, the usual trucks 3, and a body 4 mounted on the underframe 2 and adapted to tilt about either side thereof. No specific means has been provided for tilting the body but it is to be understood that any of the mechanical means known to the prior art and suitable to this type of dump car may be employed, it being understood that cars of the type on which the use of my inventionis contemplated are usually too unwieldy to be tilted by hand. Extending along each side of the body and preferably forming the major portion of theside wall thereof are doors 5 which are preferably hingedadjacent the floor of thebody and open outwardly and downwardly as the body is tilted.

In the embodiment of my invention as disclosed in the drawings, the-door controlling mechanism is mounted adjacent each end of the car body and provides independent mechanisms for eachcar door. The door mechanism shown in the drawings is a continuation in part of the door mechanism described and claimed by me in an application filed September 6, 1929, Serial No. 390,731 and it will sufiice hereto say that. these door mechanisms 9 are pivotally mounted on the body, having one end attached to its respective door and the other end in engagement with the underframe tmcontrol the-movements f the active door by the tilting of the body.

From an inspection of Fig.4 of the drawings it will be apparent that door mechanisms of this character will control: the opening door on the descending side oft the body but have no control of. the door on the rising side which necessitates the provision of .a means for maintaining the door on the rising side of the b'ody'closed during the tilting'and righting movements of the body, or in other words, while the door controlling mechanism: secured to the inactive door is out of engagement with the car underframe. Such a means is provided by the levers 6 which are pivotally'mounted at each side of the car body adjacent. the door mechanism and extend across the underframe where the opposite end of the lever 6 is pivotally mounted adjacent the side of the underframe.

By referring to Fig. 3 of the drawings it will be noted. that the door controlling mechanisms are mounted in a line transversely of the car and the locking levers 6 are disposed on opposite sides of the door controlling mechanisms with the ends of the levers alternately pivotally connecting to the underframe and car body by means of the pins 7 and 8. Projecting outwardly from each of the members 9 of the door controlling mechanism are stops H] which are adapted to be engaged by the levers 6v whose function will be further described as the description proceeds.

By referring to Figs. 3 and of the drawings it will be noted that under normal service conditions the body in turning about its respective pivots will automatically retain the members 9 in position to bear on the track I2 secured to the underframe. However, any tendency of the body to move longitudinally of the underframe would cause the rollers secured to the door members 9 to leave this track and such movement might result in injury to the door mechanism or other parts of the car body. The levers B, by reason of their position transversely of the underframe, being secured within the U-shaped members l3 and to the opposite side of the car body, will act as stops to prevent such longitudinal movement of the body. In addition to this function the levers 6 will also act as guides to the members 9 and should the body momentarily leave the underframe the levers 6 would guide the body in the return to its respective trunnions.

The particular method of mounting the car body on the underframe has no bearing on my invention since the invention can be adapted to a car which is mounted directly on the underframe and adapted to roll upon the underframe for the initial dumping movement and complete the dumping movement about a pivot mounted at the side of the body as disclosed in Fig. 6 of the drawings and described in my co-pending application filed January 31, 1931, Serial No. 512,624, or the body may be supported on spaced pivots located on opposite sides of the underframe as shown in Fig. '7, of the drawings; it only being necessary to modify the shape of the levers 6 to accommodate the differences in initial dumping movement of the car body.

Referring now to Figs. 2, 3 and 4 of the drawings, assume the body to be in the position as shown in Fig. 2 and it is desired to tilt the body about the right side of the underframe into the position shown in Fig. 4 of the drawings. In Fig. 2 the body being horizontal the levers 6, attached on opposite sides of the underframe and extending transversely of the underframe to engagement with the opposite side of the car body, are supported on the underframe and the door controlling mechanism of each door, by reason of its engagement with the underframe, maintains its respective door locked in closed position. As the body begins to tilt, the door controlling mechanism secured to the door on the left side of the body moves out of engagement with the underframe as the-body rises. The lever 6 secured to the left side of the body moves upwardly with the body and into engagement with the stop H] on the adjacent member 9 of the door controlling mechanism. Due to its connection to the body and underframe this lever 6 is held in engagement with the stop ll! of the adjacent member 9 throughout the tilting and righting movements of the body and prevents downward movement of the free end of the member 9, thus holding the attached door closed.

The member 9 of the door controlling mechanism secured to the door on the right side of the body by reason of its connection to the car body and the downward movement of the opening door, moves transversely of the underframe towards the descending door to control the opening of the door with the tilting of the body. In this manner the door member 9 moves away from the lever B which is pivoted to the right side of the body and which remains inactive during the righting and tilting movements of the car body. By referring to Fig. 4 of the drawings it will be seen that the levers 6 at their points of mounting to the underframe are slotted as at l I which permit transverse movement of the levers relative to the underframe, to compensate for any outward movement by reason of their connection to the body, during the tilting and righting movements of the car body.

During the return of the body to a horizontal position the lever 6 secured to the left side of the body moves downward with the body until it engages with the underframe. The free end of the lever 9 of the door mechanism, upon engagement with the underframe, again resumes control of the car door and holds the door closed until the body is fully returned to a horizontal position. Should the body be tilted about the left side of the underframe and same action as described would take place excepting that the movements of the door mechanisms on opposite sides of the body would be reversed.
